The armed robbery occurred about 10:30 a.m. Tuesday at the Game Stop on 20th Street.

Indian River County Sheriff's Office spokesman Tom Raulen said two armed men -- one with a rifle or shotgun and the other with a handgun -- used a cable wire to tie up the employee and filled a box with computer games.

"Interestingly, two customers had actually entered the store while the robbers were still in there and didn't realize they were robbers until they actually left," Raulen told WPBF 25 News.

A witness told deputies one of the robbers was carrying a box and said, "Someone will be right with you."

After the robbers left, the employee was able to free himself and told the customers he had just been robbed.

Game Stop's manager declined to speak about the robbery.

The employee wasn't hurt.

A sign on the door states that the store is closed until further notice.
